Reaction Steps

N-(Heptan-4-yl)-2-(mercapto)benzo[d]oxazole-5-carboxamide: To a solution 3-amino-4-hydroxy-N-(1-propylbutyl)benzamide (example 41a) (250 mg, 1.0 mmol) in EtOH was added KSCSOEt (160 mg, 1.0 mmol). The resulting reaction mixture was heated at 80° C. overnight. The solvent was removed under reduced pressure. And the residue was taken up in water. The resulting mixture was acidified with HOAc to pH ˜5 and then filtered. The residue was washed with water to afford the product as a white solid (160 mg, 55%). MS (M+H, 293.1).
